NUT- LUCK..

Specification of Letters Patent. Application filerll'uly 3,1905. Serial No. 288.141.

Patented J'une 19, 1906.

To all whom it may concern:

Be it knownthat I, WILLIAM N. KEEN, a citizen of the United States, residing at Ablta Springs, in the parish of St. Tammany and State of Louisiana, have invented new and useful Improvementsin N ut-Locks of which the following is a specification.

My invention pertains to nut-locks and it consists in the peculiar and advantageous nut-lock and nut-locking washer hereinafter described, and particularly defined in the claim appended. i

Inthe accom part of this specification, Figure 1 is a side 5 elevation of a rail-joint embodying'two of my. novel nut-locks. Fig. 2 is an enlarged detail section taken in the'pla'ne indicated by the line 2 2 of Fig. 1 and illustrating oneof the nut-locks, and Fig. 3 is a 'erspective view illustratin one oi the nut-locgiing washers removed. Fig. 4 is a perspective view of a modified washer.

Referring by letter to said drawings, and more particularly to Figs. 1 to 3 thereof, A' A are the meeting portions of two rails,and B B are splice-bars arranged at'opp'osite sides of the webs of the rails in the ordinary wellknown manner.

The nut-locks shown in Fig. 1 are identical in construction, and therefore a detailed description' of the one. shown in Figs. '2 and 3 will suifice to impart a definite understanding of both. The said lock, Figs. 2 and 3, com rises a headed andthreaded boltO, ex-

ten' "n'g through registered apertures in the splice-bars and rail-web, a nut D, mounted on the-threaded portion of said bolt, and a washer E, also mounted on the bolt and inter osed between the inner side oi. the, nut 40 an the outer side of the adjacent splice-bar. The novelty. of my invention resides chiefly in the said washer E, which is a single plate of suitable sheet metal and is preferably of a onding ,to the distance between the up er si eof the base and the under side of the ead of'each rail, so as to enable a rail to hold it against turning on the bolt. ,The

- body a of the washer is normally bent in the direction of the; length thereof and is provided with a central aperture 5, whereby it may be mounted on the bolt withits concave side a next to. the'adjacent splice-bar and its convex side (1 outermost. At the ends of'the anying drawings, forming said body a outwardlydnclined win s e are provided. These wings are normally disosed a? shown in Fig. 3 relative to the body, and hence it will be observed that when the washer is placed on the bolt and against the splice-bar they will permit of the ready interposition of a prying instrument between the ends of the washer and the bar, with a view of bending the said ends against op osite sides of the nut.

' y virtue of the body of the washer being concave-convex and the washer as a whole being formed of suitable sheet metalit will be observed that when the nut is turned up on the bolt the washer will be pressed flat between the nut and the adjacent splice-bar.

and will be placed under tension, with the result that it will serve to prevent rattling of the parts and at the same time will assist in reventing casual turning of the nut on the bolt. Subsequent to the washer being placed under tension between the nut and the splice bar, as stated, the ends of the washer are turned against opposite sides of the nut to positively lock the same. I prefer'to turn both ends of the washer against the nut as shown and described; but it is obvious that the nut may be securely locked by simply turning one end of the washer against the same.

In Fig. 4 I have shown a cruciform washer E embodying my invention, which may be used when desired in lieu of the rectangularwasher shown in Figs. 1 to 3.

It will be gathered from the foregoing that my novelnut-locking washer is inexpensive As an article of manufacture, a nut-locking washer, formed of sheet m a bod having'an aperture to recelvea bolt and a so havinga concave inner slde and a convex outersido, and a wing at one end of metal and compris- Q eeeme the body integral therewith; the said wing In testimony whereof I have hereunto set being disposed at an obtuse angle to thebody, my bend in presence of two subscribing witwhereby it is adapted to permit of the lacnesses.

ing of a prying instrument between itsel and WILLIAM N. KEEN an adjacent fish-plate and is also adapted to Witnesses;
